 The workaround you suggest didn't work.
 I reported this as a bug to Fedora bugzilla and I got the following
answer:

This sounds like you didn't load the openmpi environment module prior to

attempting to compile.  The openmpi package is compliant with the new mpi

packaging guidelines which state that there is no system wide mpi by default

and the user must select the mpi they wish to compile with by use of the

environment modules supplied by the mpi package.  That module includes the

necessary modifications to the environment to allow compilation of mpi

programs.  Can you please confirm if you see this problem after the proper

environment is loaded?

 I really don't know how to check that, but looks like the packager's
oppinion is that this isn't a packaging but of mpic++. May be this is
something new of openmpi that hasn't been taken into account in boost build
process?
 Thanks again,

 Juan

 Try reinstalling the openmpi package(s); if the problem persists, it
 could be a packaging problem, e.g., `mpicxx` configured with the wrong
 paths.

 Possibly, `mpicxx` is instructing the compiler to look for the MPI
 include files under `/usr/include/openmpi` instead of
 `/usr/include/openmpi-x86_64` (where you reported `mpi.h` is
 located). A symlink *could* be a workaround.

 Riccardo
